Asymptotic Analysis of Linear and Nonlinear Statistics. Prof. Dr. Habil. K. Kubilius 2013–

2015.

An upper bound on the tail probabilities for the normalized Rademacher sums with the

smallest possible constant is obtained. A general differential equation is found, formed from

the characteristic function, which allows us to obtain the optimal estimates of the rate of

convergence of distributions to the normal distribution for one random variable and for some

random sums of independent identically distributed random variables. Necessary and

sufficient conditions for a distribution (generalized function) of several variables with the

compact support to be positively definite are proposed. A new method was introduced in

problems where estimates are needed for finite population domains with small or even zero

sample sizes. Given training sample, the problem of classifying the scalar Gaussian random

field observation into one of several classes specified by different regression mean models and

common parametric covariance function is considered. The estimator that is similar in form to

maximum likelihood estimator for Langevin equation with standard Brownian motion and

unknown parameter θ is constructed for Langevin equation driven by fractional Brownian

motion with Hurst index H∈ (0,1/2). It is proved that for positive θ the estimator is strongly

consistent and for negative θ it is consistent. Algorithm of the estimation of stable law

characteristic parameter alfa was constructed. This algorithm is applied in the description of

the fluctuation induced flux in the edge region of the plasma cord. Asymptotic probabilities

of decomposable combinatorial structures with a fortiori prescribed properties are studied as

the sizes unboundedly increase.

Gini’s mean difference statistic was considered as an universal alternative to the empirical

variance in the settings of finite populations where simple random samples are drawn without

replacement. Specific estimation strategies for a scale of the population were constructed, and

asymptotic properties of both the statistics were explored and compared.

A new method was introduced in problems where estimates are needed for finite population

domains with small or even zero sample sizes. The method was applied for several common

cases of auxiliary information.

The exact confidence intervals for the estimator of the Orey index of Gaussian processes were

obtained. We also proved the asymptotic normality of the Orey index. We examined the

existence and uniqueness of an SDE with a polynomial drift driven by a fractional Brownian

motion (fBm) and proposed strongly consistent and asymptotically normal estimators of the

Hurst index and volatility. The existence and uniqueness of the solution of this equation didn't

follow from the already known results. For general SDE driven by an fBm, a new strongly

consistent and asymptotically normal estimator for the Hurst index was constructed under

some restrictions for the diffusion coefficient. For the Hurst index and the volatility of a

stochastic Gompertz diffusion process driven by an fBm, we gave a comparison of four

different estimators using a computer simulation. We proposed a strongly consistent point

estimator of the drift parameter of an SDE driven by an fBm. The estimator was based on

discrete observations within an interval of a fixed length.

COST action Mathematical Optimization in the Decision Support Systems for Efficient

Žilinskas. 2013-2017, http://www.cost.eu/domains_actions/ict/Actions

/TD1207?management

Energy Production and Distribution (EP&D) is among the biggest challenges of our time,

since energy is a scarce resource whose efficient production and fair distribution is associated

with many technical, economical, political and ethical issues like environmental protection

and people health. EP&D networks have rapidly increased their size and complexity, e.g. with

the introduction and interconnection of markets within the EU. Thus, there is an increasing

need of systems supporting the operational, regulatory and design decisions through a highly

inter-disciplinary approach, where experts of all the concerned fields contribute to the

definition of appropriate mathematical models. This is particularly challenging because these

models require the simultaneous use of many different mathematical optimization tools and

the verification by experts of the underlying engineering and financial issues.

COST action Onetwork for Sustainable Ultrascale Computing (NESUS) IC1305 Member

of Managing Committee Dr. A. Lančinskas. 2014-2018,

http://www.cost.eu/COST_Actions/ict/Actions/IC1305

Ultrascale systems are envisioned as large-scale complex systems joining parallel and

distributed computing systems that will be two to three orders of magnitude larger that today's

systems. The EU is already funding large scale computing systems research, but it is not

coordinated across researchers, leading to duplications and inefficiencies. The goal of the

NESUS Action is to establish an open European research network targeting sustainable

solutions for ultrascale computing aiming at cross fertilization among HPC, large scale

distributed systems, and big data management. The network will contribute to glue disparate

researchers working across different areas and provide a meeting ground for researchers in

these separate areas to exchange ideas, to identify synergies, and to pursue common activities

in research topics such as sustainable software solutions (applications and system software

stack), data management, energy efficiency, and resilience. Some of the most active research

groups of the world in this area are members of this proposal. This Action will increase the

value of these groups at the European-level by reducing duplication of efforts and providing a

more holistic view to all researchers, it will promote the leadership of Europe, and it will

increase their impact on science, economy, and society.

Research of software engineering methods arrangement with semantic modelling

methods of business management. Prof. Dr. S. Gudas. 2015-2017.

Main results:

New concepts for the modelling of a subject domain of information systems are introduced: a

management transaction and a management functional dependency (MFD). A management

transaction is considered as a sequence of information transformations aimed to implement

particular MFD. A semantic building block of enterprise management internal model is

defined as the Elementary Management Cycle (EMC). An organizational system is defined as

an entirety of management functional dependencies. Detailed Supply Chain model is

introduced for the identification of management transactions in the subject domain. The

business process modelling languages (BPMN, UML, etc.) could be used for representation of

EMC’s components.

A normalized systems development life cycle is defined as a required component of

knowledge-based IS development. The principle possibilities of using autonomic computing

approach to implement the Elementary Management Cycle (EMC) are examined. This

approach is aimed for the enterprise software system development and integration using

autonomic computing.

An approach for representing interconnections and method of semi-automated e-service

composition in the context of the water resource management information system are

proposed.

Construction of calculi and solving procedures for modal logics and lower bounds of

complexity for discrete optimisation problems. Assoc. Prof. Habil. Dr. R. Pliuškevičius.

2015-2017.

Main results:

Two finite proof search procedures for temporal logic of knowledge were constructed: one

with the invariant rule and one with looping axioms.

The sound and complete sequent calculus for half-order modal logic was constructed.

The arithmetic schemes with addition and multiplication operations approximating given

multidimensional polynomial were investigated; these schemes produce precise calculation for

Boolean vectors only. It was proved that such schemes can be exponentially stronger than the

arithmetic schemes which are calculating polynomials precisely, and exponentially weaker

than monotone Boolean schemes.

The notion of scaling transition and distributional long-range dependence for stationary

random fields on the plane were introduced in terms of scaling limits over rectangles whose

sides grow at arbitrary rate. The existence of scaling transition was established for several

classes of long-range dependent random fields, including a natural class of Gaussian random

fields with singular spectral density.

Optimal solutions in data mining tasks. Prof. Habil. Dr. G. Dzemyda. 2014–2016.

The volumes and diversity of data are rapidly increasing in our days. Optimization,

visualization and simulation methods for specific data (biomedical, financial, visual etc.) help

us to analyze and take decisions. However there is a need to get new knowledge from existing

data. Therefore it is necessary to develop new hybrid data mining and optimization methods

that can help you to find and reveal an important new knowledge. Parallel computing is also

an important tool for these challenges.

Main results:

A visualization technique for accessing solution pool in interactive methods of multiobjective

optimization has been developed and investigated.

An multiobjective optimization algorithm based on statistical rational decision theory and

visualization of the Pareto set is developed and applied to the optimal design of technological

processes.

Optimization of the maximum likelihood estimator for determining the intrinsic

dimensionality of high-dimensional data.

The visual method which can be used in the analysis of streaming data of various nature for

finding the best subsequences matching to the sample in the multivariate time series has been

developed and investigated.

Big data are generated and stored in computer networks that are saving a lot of information

which extraction and application is very important for gain of concurent ability in modern

dynamic environment of research and business. Problems of computer network analysis,

modelling and control are usually solved by methos of data mining and queueing theory.

In this project we propose to perform data analysis of epigenetic profiles in blood circulating

DNA to detect epigenetic biomarkers for early CRC diagnosis. Our goal is to apply novel

algorithmic methods that will reveal epigenetic aberrations in extended regions when

comparing cancer patients to controls. The detected regions will be used to train machine

learning algorithms and to build and evaluate an early diagnostic CRC classifier. The

bioinformatics analysis conducted in this project may provide novel, non-invasive markers,

with the potential for translation into clinical practice.
